The American Composites Manufacturers Association (ACMA) held its technical workshop at the International Bridge Conference. The workshop showcased composite (FRP) rebar as an alternative to steel rebar in concrete structures to build new bridges, as well as retrofit and rehabilitate aging bridges.
АСМА experts stressed that composites used in retrofit and rehabilitation situations extend the service life of the bridge, are faster to install and require minimal disruption to the structure. Composites also offer light weight, strength, corrosion resistance, and design flexibility.
Over the past 20 years, these properties have convinced engineers all across North America to build more than 500 bridges with composites. Thus, a bridge over the Mississippi was strengthened with FRP. Canada used a new composite material developed by a student’s team of Windsor University to rehabilitate a bridge over the Detroit River. A group of Russian scientists from the city of Perm proved that composites improve the performance of the road paving.
“Composites are a proven solution for our nation’s crumbling roads and bridges,” said Tom Dobbins, ACMA President. A year ago ACMA prepared and published ‘Guidelines and Recommended Practices for Fiber-Reinforced-Polymer (FRP) Architectural Products’. The global FRP market is estimated to grow to $91 million before 2021.
